  • Bluetooth LE utilizes an air interface as a carrier medium, malicious parties standing a relatively small distance away (e.g., three feet) are still able to eavesdrop and steal the user's Pis or passwords. Additionally, conventional technologies do not consider whether the wristlet is actually being worn by the user at the time it is used to gain access to the cellular telephone. Particularly, the wristlet may simply be held close to the cellular telephone, and need not be currently in contact with the user.

  • FIG. 2 is a flow diagram illustrating a method 50 for automatically unlocking a cellular telephone 20 by using the user's own body as a transmission medium to transmit the information needed to unlock the cellular telephone 20 according to one embodiment of the present disclosure.
  • Method 50 which is performed by the cellular telephone 20, assumes that the user is holding the cellular telephone 20 in his or her hand, and is wearing the wristlet 40 on the wrist of the hand that is holding the cellular telephone 20. Method 50 further assumes that the wristlet 40 directly contacts the user's skin.
  • Method 50 begins when the user depresses or otherwise actuates a user control (e.g., a power button or some other user control) on cellular telephone 20. Particularly, in response to detecting that the user has depressed the user control, the cellular telephone 20 establishes a BAN link 14 with the wristlet 40 (box 52). Once BAN link 14 is established, the cellular telephone 20 will, at the request of the user, generate a passcode and provide that passcode to the wristlet 40 via the BAN link 14 (box 54). Upon receipt, the wristlet 40 will store the passcode in its internal memory circuit.
  • a user control e.g., a power button or some other user control
  • transmitting the passcode over the BAN link 14 greatly increases security. Specifically, because the passcode is being sent only a very short distance on or through the user's body 12, the cellular telephone 20 can be certain that the wristlet 40 will receive and store the passcode. This mode of transmission greatly reduces the chances that a malicious third party hacker will be able to successfully intercept the passcode.
  • the user may, optionally, put the cellular telephone 20 down.
  • the user may wish to once again access the cellular telephone 20.
  • the user once again depresses the user control on the cellular telephone, and in response, receives the passcode stored at the wristlet 40 over the BAN link 14 (box 56).
  • the cellular telephone 20 then validates the passcode and unlocks the cellular telephone 20 for the user if the passcode is valid (box 58).
  • FIG 3 is a flow diagram illustrating a method 60 of how the cellular telephone 20 provides the wristlet 40 with the passcode according to one embodiment of the present disclosure.
  • method 50 begins with the cellular telephone 20 detecting the presence of the wristlet 40 and activating a BAN transceiver (see Figure 5) responsive to the user depressing a user control, such as the power button of the cellular telephone 20, for example, that may wake the cellular telephone from an idle state (box 62). More particularly, the user control is operatively connected to the BAN transceiver such that depressing the user control automatically activates the BAN transceiver.
  • the BAN transceiver Upon activation, the BAN transceiver transmits signals at timed intervals that are received by a corresponding BAN transceiver in wristlet 40. Once detected, the BAN transceivers establish the BAN link 14 between them and pair with each other (box 64).
  • the cellular telephone 20 is then programmed to display a prompt to the user requesting whether the user wishes to utilize the wristlet 40 to automatically unlock the cellular telephone 20 whenever the user subsequently depresses the user control to access the cellular telephone 20 (box 66). If the user declines, the cellular telephone 20 will present the user with the passcode screen lock, as is conventional (box 68). In such cases, the user will be required to manually enter the passcode, as is conventional. If, however, the user indicates the he or she wishes to utilize the wristlet 40 as a subsequent unlock mechanism for the cellular telephone 20 (box 66), the cellular telephone 20 will create the passcode and send the generated passcode to the wristlet 40 via the BAN link 14 for storage in memory at the wristlet 40 (box 70).
  • FIG 4 is a flow diagram illustrating a method 80 for providing the passcode from the wristlet 40 to the cellular telephone 20 to automatically unlock the cellular telephone 20 according to one embodiment of the present disclosure.
  • the cellular telephone 20 once again determines that the user has depressed the user control, (e.g., the power button or other user control) on the cellular telephone 20 (box 82).
  • the cellular telephone 20 establishes, or re-establishes, the BAN link 14 using the known protocol and actions of its BAN transceiver (box 84).
  • the cellular telephone 20 generates and sends a request message to the wristlet 40 via the BAN link 14 requesting the passcode from the wristlet 40 (box 86).
  • the wristlet 40 then retrieves the passcode from its memory and sends the passcode to the cellular telephone 20 via the BAN link 14 (box 88).
  • the cellular telephone 20 then checks to determine whether the received passcode is valid (box 90). If not, the cellular telephone 20 simply displays the user with the conventional manual entry screen for the passcode. Otherwise, the cellular telephone 20 bypasses the conventional screen lock functionality and automatically unlocks the cellular telephone 20 for the user (box 94). So unlocked, the user is able to access whatever information and data is on the cellular telephone 20 that he or she wants to access.

Abstract

Selon l'invention, un utilisateur d'un téléphone cellulaire a également un dispositif périphérique, tel qu'un bracelet ou une bague, par exemple, qui est porté sur le corps de l'utilisateur et est en contact avec ce dernier. Lorsque l'utilisateur appuie sur une commande d'utilisateur, telle qu'un bouton d'alimentation ou une autre commande sur le téléphone cellulaire, une liaison de communication de réseau de surface corporelle (BAN) est établie entre le téléphone cellulaire et le dispositif périphérique. La liaison BAN utilise le corps de l'utilisateur comme support de transmission pour transporter des données entre le téléphone cellulaire et le dispositif périphérique. En outre, un code de passe stocké au niveau du dispositif périphérique est envoyé au téléphone cellulaire sur la liaison BAN. Si le code de passe est valide, le dispositif contournera un écran d'entrée de code de passe et déverrouillera le téléphone cellulaire pour l'utilisateur.
